Description

Technical Field

[0001] The invention relates to the technical field of cooling towers, in particular to a de-whitening and mist-eliminating cooling tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the principles of evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate waste heat generated in industry or refrigeration and air conditioning to lower the water temperature through evaporative heat dissipation to ensure the normal operation of the system.

[0003] Traditional cooling towers rely primarily on water evaporation to dissipate heat. When circulating water directly exchanges heat with the air through the surface of the packing, a large amount of water is lost in the form of water vapor, causing the hot and humid air discharged from the cooling tower to quickly condense in a low-temperature environment, forming a large amount of white mist. Existing defogging devices typically use finned heat exchangers to condense water vapor, but these devices are large and have high resistance. The defogging effect is significantly reduced at low temperatures in winter, and the condensed water cannot be recovered. This not only causes serious visual pollution, but also becomes a carrier for the diffusion of pollutants when the atmosphere is relatively still, exacerbating the formation of haze and failing to meet environmental emission requirements. In view of this, the present invention proposes a defogging cooling tower. Summary of the Invention

The term "perpendicular" simply refers to a more perpendicular relationship between components than "parallel," not that the structure must be perfectly vertical; rather, it can be slightly tilted.

[0041] See also Figure 1 and Figure 2 The present invention provides a technical solution: a de-whitening and mist-eliminating cooling tower, comprising a water tray 1, a plurality of feet 11 fixedly connected to the side wall of the water tray 1 to improve the stability of the tower body, a fixing seat 12 is installed on the side wall of the water tray 1, and an outlet pipe 121, an inlet pipe 122 and a sewage pipe 123 are embedded on the fixing seat 12, the outlet pipe 121 is connected to the return pipe of the circulating water system, and a check valve is set at the pipe mouth to prevent water from flowing back, a central pipe 3 is vertically arranged in the middle of the water tray 1, and the bottom of the central pipe 3 is connected to the inlet pipe 122 through a valve 31, which is responsible for introducing hot water to be cooled, and the sewage pipe 123 is located in the water tray 1 The lowest point of the bottom is used for regular discharge of deposited impurities. The pipe mouth is equipped with a manual gate valve. The outlet pipe 121, the water inlet pipe 122 and the sewage pipe 123 are all connected to the inside of the water tray 1. A plurality of pillars 13 are arranged circumferentially on the top of the water tray 1. The tops of the plurality of pillars 13 are commonly connected to the shell 2. A plurality of reinforcing ribs 21 are arranged circumferentially on the side wall of the shell 2. A louver air inlet is opened between the shell 2 and the water tray 1 (arranged between adjacent pillars 13, not shown in the figure). The inclination angle of the louver is set to prevent rainwater from intruding. The top of the shell 2 is open and cooperates with the fan assembly 8 to form an upward airflow channel.

[0042] like Figure 3 and Figure 6 As shown, a bracket 4 is installed on the central tube 3, and the bracket 4 is arranged in the shell 2. The bracket 4 includes multiple groups of first inclined plates 41 and second inclined plates 42 arranged obliquely, and the first inclined plates 41 and the second inclined plates 42 are staggered. The distance between the top of each group of first inclined plates 41 and the second inclined plates 42 is smaller than the distance between the bottom of the first inclined plates 41 and the second inclined plates 42. A first bracket 43 is commonly provided on the first inclined plates 41 and the second inclined plates 42. The ends of the multiple first brackets 43 are commonly connected to a first hoop 44. The first hoop 44 is connected to the central tube 3. The side wall of the tube 3 is connected. It should be noted that the outer diameter of the top of the bracket 4 is larger than the outer diameter of the filler 5, ensuring that the filler 5 can be placed stably on the top of the first inclined plate 41 and the second inclined plate 42. The air flow channel is formed between the first inclined plate 41 and the second inclined plate 42, which can guide the air to flow along the gap between the ends of the first inclined plate 41 and the second inclined plate 42, and at the same time limit the water treated by the filler 5 to flow through the gap, thereby extending the contact time between the air and the water, ensuring that the heat of the tail water is fully absorbed, and improving the cooling quality.

[0043] like Figure 4 and Figure 5As shown, a filler 5 is provided above the bracket 4. The filler 5 is sleeved on the central tube 3, and the outer diameter of the filler 5 is smaller than the outer diameter of the bracket 4. The filler 5 is composed of multiple groups of corrugated plates, and a cross design is adopted between the multiple groups of corrugated plates. The surface of each group of corrugated plates is provided with an anti-scaling coating. Furthermore, the water to be treated flows in from the top of the filler 5 and flows along the surface of the corrugated plate to form a uniform water film. At the same time, under the cross setting of the corrugated plates, the water film continuously changes direction during the flow process, thereby increasing the contact area with the air and strengthening the heat and mass exchange between the air and the water film.

[0044] like Figure 7 As shown, multiple groups of guide plates 6 are installed above the filler 5, and the multiple groups of guide plates 6 are commonly connected with a second bracket 61, and the second bracket 61 is arranged obliquely. A second hoop 63 is fixedly connected to the side wall of the guide plate 6 near the central tube 3, and the second hoop 63 is connected to the side wall of the central tube 3. The multiple groups of guide plates 6 are arranged in a circular ring shape, and the multiple groups of guide plates 6 are all arc-shaped plates. The diameter of each group of guide plates 6 increases to form an umbrella-shaped superimposed structure. The distance between the guide plate 6 and the filler 5 near the inner wall of the shell 2 is smaller than the distance between the guide plate 6 and the filler 5 near the central tube 3. It should be noted that by setting multiple groups of arc-shaped guide plates 6, the middle part of the guide plate 6 is lower than the height of the two ends, and an annular water storage tank can be formed. When the spray assembly 7 sprays the hot water to be treated, the hot water will first contact the guide plate below under the guidance of the nozzle 73 itself. The water tank on the guide plate 6 is filled and eventually overflows from both sides of the guide plate 6 to form a water curtain covering the top of the filler 5, thereby improving the uniformity of hot water flowing into the filler 5 and avoiding the heat exchange with the air affected by excessive accumulation of hot water on the top of the filler 5. Furthermore, the position of the guide plate 6 corresponds to the position of the upper heat pipe 91. In the subsequent processing process, the condensed water dripping from the heat pipe 91 will fall into the water tank on the guide plate 6, thereby mixing with the hot water to be processed, lowering the temperature of the hot water and reducing the subsequent heat exchange load. At the same time, the condensed water is recycled to improve the cooling effect and resource utilization. Furthermore, through the guiding effect of the lower surface of the guide plate 6 on the air, the rising airflow can be converged to the middle of the cooling tower, thereby better contacting the upper heat pipe 91 to ensure condensation of the hot air.

[0045] like Figure 8As shown, a spray assembly 7 is provided on the top of the central tube 3, and the spray assembly 7 is provided above the guide plate 6. The spray assembly 7 includes a connecting seat 71 provided on the top of the central tube 3, and a plurality of sprinkler pipes 72 are circumferentially provided on the connecting seat 71. The plurality of sprinkler pipes 72 are all connected to the interior of the central tube 3. The bottoms of the plurality of sprinkler pipes 72 are respectively connected with a plurality of nozzles 73, and the plurality of nozzles 73 are equidistantly arranged. It should be noted that hot water enters the connecting seat 71 from the central tube 3, and through the setting of the internal partition of the connecting seat 71, the sprinkler pipes 72 at different positions are evenly diverted, thereby reducing the flow deviation of different sprinkler pipes 72, and coordinating the plurality of nozzles 73 equidistantly arranged to improve the uniformity of hot water spraying. Furthermore, through the buffering effect of the guide plate 6, the splashing caused by the contact between the hot water and the filler 5 can be reduced, thereby preventing the hot water from absorbing heat from the filler 5 and flowing directly into the water pan 1 below along the inner wall of the shell 2.

[0046] In addition, a fan assembly 8 is provided above the spray assembly 7. The fan assembly 8 includes an assembly box 81. A plurality of inclined rods 82 are fixedly connected to the side wall of the assembly box 81. The ends of the plurality of inclined rods 82 away from the assembly box 81 are fixedly connected to the inner wall of the shell 2. A motor 83 is fixedly installed inside the assembly box 81. The motor 83 adopts a Y2-132S-4 three-phase asynchronous motor with a protection level of IP55 suitable for operation in a hot and humid environment. The motor 83 is fixed to the top steel plate of the assembly box 81 by bolts, and the output shaft extends vertically downward to the outside of the assembly box 81. The motor 83 The output shaft is connected to the rotating seat through a coupling, and a plurality of fan blades 84 are arranged circumferentially on the rotating seat. A bearing seat is provided below the rotating seat, and a bearing is installed in the bearing seat, and the bearings are respectively connected to the connecting seat 71 and the rotating seat. By arranging a deep groove ball bearing seat below the rotating seat, the outer ring of the bearing and the rotating seat have an interference fit, and the inner ring and the shaft sleeve at the top of the connecting seat 71 have a clearance fit, which can improve the stability of the fan blades 84 during operation. The airflow driven by the operation of the fan blades 84 is guided by the guide plate 6 to smoothly transition to the middle of the cooling tower and finally reach the heat pipe 91 for condensation treatment.

[0047] like Figure 9As shown, a condensing assembly 9 is provided above the fan assembly 8, and the condensing assembly 9 includes a spirally arranged heat pipe 91, and the heat pipe 91 is provided at the top of the shell 2, and a plurality of extension pipes 92 are vertically provided at the upper end of the heat pipe 91, and the plurality of extension pipes 92 are connected to the interior of the heat pipe 91, forming a three-dimensional condensing network to increase the heat exchange area, and a plurality of groups of third brackets 93 are provided on the circumference of the heat pipe 91, and each group of third brackets 93 are arranged on the same meridian of the heat pipe 91, and the ends of the plurality of third brackets 93 away from the heat pipe 91 are fixedly connected to the inner wall of the shell 2 respectively. It should be noted that from the louver at the bottom of the shell 2 After the incoming air passes through the filler 5 and undergoes heat exchange with the hot water, the temperature and humidity are relatively high when it flows to the top of the cooling tower. By setting the heat pipe 91 in a disc shape and extending it outward along a spiral line, after the surface of the heat pipe 91 comes into contact with the hot and humid air, the ethanol filled in the pipe absorbs heat and evaporates, forming steam that moves toward the condensation section at the extension pipe 92. After the steam condenses into liquid, it flows back along the pipe wall into the heat pipe 91 again. At the same time, the water vapor molecules in the hot and humid air will condense into water droplets, adhere to the surface of the heat pipe 91 and eventually drip down to the guide plate 6 at the corresponding position, which can effectively reduce the white mist of gas discharged from the top of the cooling tower.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
